CNPE — Cloud Native Platform Engineer
This Is What the CNPE Exam Looks Like
One-line summary
CNPE is a hands-on exam, and you must score at least 64% within 120 minutes to pass.
Why read this first
The most common failure in certification study is not from not knowing the content but from walking in without knowing the shape of the exam. If you do not know what the passing score is, how tight the time is, or which domain has many questions, you cannot set your preparation priorities.
Official specifications
| Item | Value |
|---|---|
| Format | Hands-on |
| Time limit | 120 minutes |
| Passing score | 64% |
| Volume | 15–20 tasks |
| Exam fee | $445 (includes 1 retake) |
| Validity | 2 years |
These values come from the candidate documentation at docs.linuxfoundation.org. The certification
introduction page does not list the passing score or the number of questions, so if you prepare by looking only at that page,
you walk into the exam room without knowing the passing score.
Domain weighting
| Domain | Weight | | |---|---:|| | GitOps and Continuous Delivery | 25% | | | Platform APIs and Self-Service Capabilities | 25% | | | Observability and Operations | 20% | | | Platform Architecture and Infrastructure | 15% | | | Security and Policy Enforcement | 15% | |
More questions come from the domains with larger weights. Use these ratios as the basis when you allocate study time. This practice exam also distributes its questions in the same ratios.
Where the answers split
When you grade a practice exam, the questions you get wrong cluster in one form. You get them wrong not because you do not know the content but because you miss which of two similar concepts is being asked. When you read a question and one of the pairs below comes to mind, first separate them by the criterion in the third column.
| This | That | What separates them |
|---|---|---|
| Platform API | Internal implementation | The contract promised to users is the API |
| Abstraction | Concealment | If you reduce the choices it is abstraction, if you make it invisible it is concealment |
| Tenancy boundary | Namespace | If billing, permissions, and isolation go together, it is tenancy |
| The platform team's SLO | The product team's SLO | What the platform promises is the platform's SLO |
This does not mean you should memorize the table. If you mark which pair each question you got wrong fell under, the place to study again becomes much narrower than a domain name.
What you can look at while solving
During the exam you can open the documents below. You view them in Firefox inside the remote desktop.
kubernetes.io/docskubernetes.io/blog과제별 Quick Reference 링크(the Quick Reference link for each task)
There are three rules. Search inside the documentation sites is allowed, but you must not click external search results. The Korean translation can also be viewed, but the English is the latest, so it is recommended. And a Quick Reference link is given separately for each question, and that link is added to the allowlist.
Being able to look at something and being able to find it are different. Rather than memorizing content, getting familiar with the structure of the documents saves time.
What you actually experience at the exam
Many people lose time by panicking at the procedure even though they know all the content.
The exam is taken with online proctoring on PSI's Bridge platform. The proctor's video verification procedure takes up to 30 minutes, and during it the questions do not open and the time limit does not start. Even so, you should keep your schedule clear for 30 minutes of check-in plus the exam time.
At check-in there are four things to confirm. Agreeing to the non-disclosure agreement, a government-issued ID that exactly matches the registered name, showing the room by turning the webcam around, and closing unapproved software. Because of the last item, turning off background programs such as Slack or cloud sync in advance saves time.
There are a few conditions that are easy to get caught on when taking the exam in Korea. The ID must be signed, so a passport is the safest. You can use only one monitor, and dual monitors are not supported. There must be nothing both on top of and under the desk, writing on paper is forbidden, and reading the questions aloud is not allowed either. On a corporate network or VPN, access to AWS S3 may be blocked, and you can get caught in the pre-check.
You can change a reservation only up to 24 hours before the start. And if you make a reservation and do not show up, not only do you lose the exam fee but your retake eligibility also disappears. The result arrives by email within 24 hours after the exam ends.
One retake is included in the exam fee, and you must complete both the attempt and the retake within 12 months of the original purchase date. There is no official waiting period, so you can retake right after you receive the result. Rather than putting it off because you are not perfectly prepared, it is often better to take it once and see which domain is weak.
The certification is valid for 2 years. On top of this overlaps the CARE program introduced in 2026. If you pass CKA or CKAD, KCNA is renewed automatically, and if you pass CKS, KCSA and CKA are renewed automatically. However, you must earn the lower-level certifications first for this chain to work. If you earn CKA first and KCNA later, that CKA will not renew KCNA. If you are aiming for Golden Kubestronaut, this order determines your renewal burden for the next several years.
How to use this practice exam
The time limit is set the same as the real exam. The remaining time is visible at the top of the screen, and when time runs out it is submitted automatically and unsolved questions are treated as wrong. The real exam likewise grades only what you solved at that point.
It is important to sit and work through to the end in one go. If you look things up as you go, the score goes up, but that score does not predict the real exam. What you want to check is not whether you know it but whether you clear the passing score within the time limit.
After you read the explanations for the questions you got wrong, study again the domain those questions belong to.
